I have a WPF form. It handles the KeyUp event and if the released key was Escape, it closes itself.
Also this form has a button to show some Windows Form as a dialog. It does handle the Escape key in the same way.
What happens is that when I press Escape when in the child dialog, both windows close. I expect only the child Windows Forms window to close in this case.
What’s the proper way to handle this?
The easiest option for WPF is set the button property
IsCanceltotrue. Then if you pressESCthe form would be closed.
